The problem with that argument is that a Tesla isn't nearly as clever as a human. I have never thought a white tractor trailer disappeared as it crossed in front of me against a bright sky. I know that I should drive a little bit slower on Halloween evening because there are kids running around. I know that I need to be a little more cautious driving past the playground or dog park. I have object permanence.

As it is, AI just isn't smart enough to rely on only vision and they ought to be taking advantage of every economically viable sensor to make up for the difference. Hell, I thought the goal was to do better than humans?
